INCINERATOR.

Application filed November 20,1925. Serial No. 70,381.

This invention relates to a refuse incinerator and has for its objectthe production ofianlapparatus for this purpose which en ables householcrefuse and the li.ke to be destroyed quickly, economically and withoutcreating any odors which are perceptible either outside of'theincinerator or on the exterior of the building in which the apparatus isinstaller.

In the accompanying drawings: Figure 1 is a vertical'section ofianincinerator embodying my improvements.

Figure 2 is a horizontal section taken on the correspondingly numberedline in Fig. 1. Figure 3 isa fragmentary vertical section taken on line38 Fig. 1.

In the following description like reference characters indicate similarparts on the several figures of the drawings. r v

The enclosing casing of this incinerator comprises a bottom 10-, anuprigl'it body or wall 11 preferably of cylindrical form rising from thebottom and a top 12 forming. a

closure for the upper end'of the wall. The smoke is carried away fromthis casing to a chimney or elsewhere by a smoke pipe 13 whichcommunicates with the central part of the space withinvtheuppier partofthe casing and preferably extends'upwardly from Within this casingisarranged a refuse receptacle 1%, preferably of cylindricalform, whichterminates at itslower" end above the bottom of the casing so astoforinian ash oi't l5'therebetween and'terminates at' its'u 1 i r J.perend-below the LOP of'the casing sofas to form .a combustion chamber16 therebetween, and alsoseparated at its sideby an annularspace- 17from the adjacent part of the body ofthe casingwhichr-forms a verticalpassage extending from: the 'ashpit to theicomhnr'e tion' chamber.

This receptacle is providedwith' a plu rality of. perforations 9 whichare distributed over this receptacle; and cover the required area of thesame-from the supper edge there-' ofltowardlitsilower.edge;

Atits T lower end tlie'P-refuse" receptacle is provided with" a vgratewhichxispreferably constructed in the formofftwo sectronslS 18 arrangedparalleland each having a hollow shaft or pipei19 whichisjournaled in:-suitable bearings :and: provided with out; letiopenin'gsKQO wherebythisishaft serves-"as burner-1 byrcsans. of: which ztheega z introsduced to thehollowshaft burns in flamesat these outlet openings andheats the garbage and other refuse which is arranged abovethe burners inthe receptacle.

In the upper part of the front side of the casing and receptacle a feedchute 21 extends through the same through which the refuse to bedestroyed is introduced into the receptacle and which is normally closedby a door 22.

Air is conducted from the exterior of the incinerator to the space inthe upper central part'of the receptacle and easing above; the normalheight ofthe pile of refuse in the receptacle by'an air supply pipehaving an upper upright section 23 arranged centrally in'the receptacleand having'an outlet at its upper end which terminates above the normallevel. of the pile of refuse in the receptacle and preferably below theupper endof thesameand above the top ofthe feed chute 21 I and'alsohaving a'lower horizontal section 2% which extends laterally from thegas delivery pipe '25" forming part of an I auxiliary burner. which. gaspipe terminates atits end within the air pipe section 23 and adjacent tothe upper end' of the same and has its lower end passing through and'preferably secured to the lower part of this air pipe. Gasis supplied to'this'delivery pipe by a horizontal supplypipe 26 eXtendi1'ig,later-ally from the lower endof the delivery pipe through the adjacentpart-of the 'recepe tacl'e and casing and provided on the exteriorof'the latter with a gas and air mixer 27 by means o-fwhich mixed gasand'air isad mittedto the supply pipe 26 whichburns'in a flame at theupper end of thedelivery pipe 25. 1 I r W'ithin lthe space inthe'upperpart of the casing and betweeathe upper end of'the Y form, as shown'bydotted linesin'Figg2 and which projects laterallybeyond these pipes inall; directions so that the lameissuing from them-p per end of I thepipe 23 will be ion deflected laterally therefrom in all directions.

This baf le may be supported in any suitable manner for example by meansof hangers 29 secured to the lower end-of the smoke pipe, as shown inFig. 1. Within the smoke pipe and preferably adjacent to' its lowerinlet end is arranged a spreader 30 having preferably the form of adownwardly tapering cone so as to form an annular passage betweeen theperiphery of the upper large part of this spreader and the adjacent partof the bore of the smoke pipe. This spreader may be held in place bymeans of one or more brackets or arms 31 secured to the smoke pipes asshown in Fig. 1.

In the operation of this incinerator the flames from the burner pipes 19strike the underside of the garbage resting on thegrate within thereceptacle and cause the same to be heated which operates to dry thesame and generate vapors which are driven off from the refuse. At thesame time the air heated by the flames of the grate burners passes fromthe ashpit upwardly through the annular passage 17 between thereceptacle and the casing to the combustion chamber at the upper end ofthe casing and receptacle while some of this heated air also passes fromthe passage 17 inwardly through the openings 9 to the side of the refusein the receptacle and also into the space within this receptacle abovethe refuse therein, While drying of the refuse is promoted and anyvolatile gases contained therein are liberated and caused'to separateand rise from the refuse, particularly in the case of kitchen garbage.

While flames are thus issuing from the grate burners, a flame burnsat'the upper end of'the auxiliary burner pipe 25 which flame heats theair supplied by the auxiliary air supply conduit 23, 241. This centralflame and heated auxiliary air upon issuing from the upper end of thedelivery pipe 23 is deflected laterally in all directions by the bafile28 so as to form a radiating stream of flame and heated air whichspreads like a blanket over the top of the refuse in the receptacle. As.a result the combustible gases rising from the refuse due to heating anddrying of the same causes the gases to become mixed with the heated airissuing from the central pipe, the openings in the receptacle and theupper end of the side passagel'? and produce a mixture which is highlycombustible and constantly ignited by the flame of the central burnerpipe 25.

The heatresulting from this combustion in the combustion chamber abovethe pile of refuse in the receptacle aids materially in. promotingdrying of the refuse, such as wet or moist garbage, whereby the mass ofrefuse isgradually consumed, or destroyed from the top of the piledownwardly to the grate,

and when this is completed the ashes or residue may be dumped from thegrate into the ashpit and then removed from the latter through an ashpitdoor 32 which has the usual air inlet openings 34.

By thus applying a flame and auxiliary heated air to the top of therefuse in addition to applying heat to the bottom and sides of samepractically every trace of odor bearing gas is burned immediately uponleaving the mass of refuse, thereby preventing the escape of anyunconsumed odor bearing gases to the exterior of the apparatus or thebuilding containing the same, and rendering the use of such incineratorswholly unobjectionable in residental sections of a community.

The flames resulting from the vburningof such gases continue theirfunction upon leaving the combustion chamber and passing around the edgeof the deflector or battle and over the latter and upwardly through thesmoke pipe.

As the flames, gases and heated air pass upwardly through the smoke pipethe same are again spread by the spreader therein instead of beingpermitted to pass in the form of a core or solid stream through the"central part of the smoke pipe, therebv further promoting intimatemixture of the heated air with the combustible elements in the gasesderived from the garbage or other refuse, and enabling the same to beignited by the flames and consumed so that no odors are perceptible onthe exterior of the apparatus.

Moreover this apparatus permitsof utilizing the heat units in the refuseto the maximum extent for destroying the same or rendering it innocuous,thereby effecting a considerable saving in cost-of gaseous fuel fordoing this work.
